lowing to hc a fulh clcar, and exact ill-scription of thcv invention, such as will cnuhlc; othcrs Slflllttl in thc art to which it appcrf tainsto nlakc and use thc sanic.

This invcntion is fora nicthod t'or rvmovin; tho meat)" inattcr from thc shcll ot' rrus tacca gcncrally, hut for simplicity ol dcscription I simply rcfcr to the common crabby way of llltlril'iltltlll, however that thc nicthod is cqually applicahlo for use in connection with thc shut-kin of lohstcrs. shrimp and siniil'ar tish.

In a scparatc application, lilcd May 27. 1909, h'crial Xunihcr, ltltv' Tllt and covcring apparatus for shut-king crustacca. l havc pointcd out various uillicultics. now arising. in shut-hing crustacca for purposcs of canning. and hrictlv slatcd thc prvscnt lncthod has hccn tlt.'l50 l for thc purposc ot' (t).i\'t'll icncc and clcanlincss.

Many diti'crt'nt forms o apparatus nnrv htemployed in carrying' out thc prcscnt methoth and in thc apparatus application rcferrcd to l havc illustratcd and s rihcd different forms both for the inanipuhtt-ion of the crnstacea being shuckud and also spocilio means for retainingthc crustaroa sccurolv on its support, but in the prcsvnt applioation, for thc purposc of simplicity of illustration I shall Simply rofcr to onc of thcsc forms. I shall now doscrihc my niothod illustrating thc accoinplishnicnt of the same by the accompanying drawings, in which thc 5211110 numerals refer to the same parts in the two views, and in which- Figure 1 is a view in side clcvat'ion, the cylindrical guard hcing shown in longitudi nal section, to show the intcrnal lllttltillllhlll. Fig. 2 is a transversc sectional view through the carrier support, one of thc cat-rims hr-ing shown in; full lines in thc position it, assumes when the machine is not running. and in dotted lines in the position it assumes when the machine is runniiw.

it will he ohrion that in the particular apparatus -hown or carryin out th pre nt method. that when he driving shall 1 i rapidly rotated the carrier support mounte on the letachahle shaft will also rtpidl rotated. which will cau e the winging carriers 17 to swing np\\ard and nilt\f;ll'|li owing to'rentri t'ngal action. until th a sume the po ition hout in dotted line in l'i J. in which po-ition the action t t'tiltl'il l fllll force will throw the meat from out o! the re trained shells. so that the tltt'.tl i deth-t-ted i.' the guard into the receiving pans. while the iltilr are retained n the supports and the supports may he removed its an entir ly with the denuded shells. hilc a new support w th tilled shells may he placed in the machin and the method ol traction eontintu-d while other support are being prepared h) the 'llu'l'utiu's.

Having thus deserihed one form ol' at paratus with which ut method taa he carried out. what I claim i l. The method ot eparating the meaty 'tnalter from the shell of erustaeea. which consists of denuding the hotly portion of its l-acl: shell and appendages: tn dn tdtug the -portiou to he shut-Led. on a line transversely of the lohes or cells; in ecuring the shell portion on a suitahle support. which will permit the free eseape ot' suid'nn-at matter l'rotn aid cells; and tinally creating a removing fort-e directed suhstantialty in alinementwith the tubes or cells. for removing said meaty tnatter while retaining the shell.

:3. The method of separating the meaty matter from the shell of crustacea, which consists in denuding the body portion of its hack shell and appendages; in s 'tg-ataling the portion to he shucked on a line trans\'ersel ol' the lobes or cells; in securing the shell portion on a support which will permit the free escape. of said meaty matter from said cells; and finally im'artine; a rotary motion to said support whi e restraining theshelfs. l

:3. The method of separating the meaty matter from the shell f ernstacea, which consists in deuuding the hotly portion of its hack shell and appendages: in dividing the portion being shuelt'ed on a line transversely of the lobes or cells; in Ltltl'lllg the shell portion on a rotary support with the lohes or cells containing meaty matter disposed t iuh tantiall radial to said support which will permit tlte free escape of said meaty matter from said cells; and linally impart ing a rotar) motion to said support [or throwing out th meaty matter \thile restraining the. shell.

l. The method of Sllntlztiittg' the meaty matter from the shell of Cl|l:i.Zlt;t3;l which eonsists in cooking! the same to loosen the areal in the cells; th n dividing the portions to he shut-lied on a line p: sing transversely of the lohes or cells: then securing the shell portions on a suitable support which will ermit the free escape ol said meaty matter from said cells; and tinally creating a retno\'in l'orce directed substantially in alinement with the lohes or cells for removing the meaty matter whil restraining the shells.

I The method or separating the meaty matter from the shell of erustaeea, which consists in deuuding the body portion of its atch shell and appendages; in dividing the portions heiu; huelted on a line passing ll hlllllliltlhv central ot' the crab and trans- \er.--el lletn' t'n the opposed lohes or cells; in :-tt'llt'lti the shell portions on a support which will permit the free escape of said meaty matter from said cells; and finally ereating a removing fort-e directed substantially in alinententwith the tubes or cells for removing the meaty matter wh restraining the shells,

H. The method of separatim the meaty matter from the shell of crustacea, which consists in cooking the crahs n liciently to ltlthlll the meat "in the cells; in dennding (in: body portion of its back shell and appendages; in dividing the portions to be shut-lied on a line passing suhstantially hansrersely ol the opposed lohes or cells; in securing the shell por ions on a suitable support; and tinally creating a removing force dire'eted substantially. in alinctnent with the lobes t'or renuwiug the. meaty matter whilerestraining the shells.

in testimony whereof, I ailix my signatnre. in presence of two witnesses.
